  • Abstract:
    This report presents the evaluation results of the Phoenix, Arizona Metropolitan Model Deployment Initiative (MMDI). The

    MMDI was a three-year program of the Intelligent Transportation Systems (ITS) Joint Program Office of the U.S. Department

    of Transportation. It focused on aggressive deployment of ITS at four sites across the United States, including the

    metropolitan areas of San Antonio, Seattle, NY/NJ/Connecticut as well as Phoenix. The focus of the deployments was on

    integration of existing ITS and deployment and integration of new ITS components. Nineteen public sector agencies and

    thirteen private firms participated in AZTech, the name given to the Phoenix MMDI.

    The evaluation encompassed fifteen AZTech projects. Eight projects provided advanced traveler information services; four

    projects were concerned with traffic management systems; and three deployed transit management systems. Traveler

    information services used public traffic and transit data from the central AZTech server along with data from the private

    sector. To address diverse market segments a wide range of dissemination technologies was used, including a personalized

    messaging system, Trailmaster Web site, commercialized Web page, Traffic Check Cable TV, in-vehicle navigation devices,

    Fastline personal communication device, transit status information, and travel information kiosks. AZTech's traffic

    management systems included eight "Smart Corridor" projects, three of which were included in the evaluation. Traffic

    management systems were deployed to provide interjurisdictional traffic signal coordination along major arterial roads in the

    region and to implement a computer-aided incident management system to facilitate efficiency and accuracy of incident

    investigations. Three transit management systems were deployed, all with automatic vehicle location technology to aid in

    dispatch and to provide status information to travelers. Integration among these various projects was a key feature of the

    AZTech program.

    The evaluation focused on six key study areas: network efficiency, safety, energy and emissions, customer satisfaction,

    costs of deployment, benefit/cost analysis, and institutional lessons. The intent was to evaluate changes in each of these

    areas brought about by deployment of new projects, as well as integration of both new and existing projects. This report

    presents the observed impacts of each of the fifteen MMDI projects and their integration and provides conclusions and

    recommendations based on the results.
